888 Holdings PLC shareholders sent a warning to Chair Brian Mattingley Tuesday, with over 20% voting against his re-election at the online gambling company’s annual general meeting.

At the AGM, 53.4 million shares voted against Mattingley’s re-election, which represents 21.3% of the votes cast.

He was appointed non-executive chair of 888 in March 2016 having been chief executive officer since March 2012. He joined the 888 board in the summer of 2005.

The online gambling firm said it will “hold discussions with its major shareholders in the coming months in order to understand the reasons behind this result”.

In the beginning of March, 888 said its profit grew significantly in 2018 following the implementation of a cost reduction plan, but revenue come in 2.2% lower due to the challenging market conditions in the UK and the departure of a long-term partner.
